Since my civilians are happily transiting a system with a wormhole in it I have moved my defensive fleet right to the wormhole. Never did that before, so I am no wondering if a wormhole transit will give them the same fire/sensor delay as a jumppoint transit would.

I do not know if they suffer the same delay or not. But I can confirm you sometimes do not get a proper interrupt when they do transit. I have had times where on a 1/5/30 day time click a transit happened but looking at the system map it is clear there was sometime extra given between the transit event and the interrupt as the spoiler race ship was some distance from the wormhole itself thus making my defence net a little pointless.

They don't appear directly on the wormhole. They can appear up to two million kilometres away.

Dang, thx, so essentially my fleet might be fairly useless where it is, but there is no way to stop the civs from using this system to travel through. Oh well, at least I have a decent number of box launcher FACs which might do some damage and enough PD to stop 1-2 large missile ships (meaning I will be dead if there are 3 large ships).

I've had invaders appear near old, previously closed wormholes, so that may have been what happened.

You can Ban bodies, which should prevent traffic to and from Bodies in that system, but not through it. The only way Civs will avoid system is in the aftermath of combat, which would raise the system danger level, because who in his right mind would want to pay those insurance premiums?!
